Synopsis
</h2>
<p class="indent" style="white-space:nowrap;">
<code>AX_BOOST_PROGRAM_OPTIONS</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
Test for program options library from the Boost C++ libraries. The macro
requires a preceding call to <a href=
"ax_boost_base.html">AX_BOOST_BASE</a>. Further documentation is available
at <<a href=
"http://randspringer.de/boost/index.html">http://randspringer.de/boost/index.html</a>>.
</p>
<p>
This macro calls:
</p>
<pre>
AC_SUBST(BOOST_PROGRAM_OPTIONS_LIB)
</pre>
<p>
And sets:
</p>
<pre>
HAVE_BOOST_PROGRAM_OPTIONS
</pre>
